rl0: watchdog timeout

Hi,
Since I moved a box up to HEAD, I've been seeing lots of these in my dmesg:
rl0: watchdog timeout
The network still works, but sometimes it wreaks havok with machines connected
to it. It seems to happen when I stress the NIC a lot (i.e. copying lots of
data over via NFS).
I've also seen this in PREVIEW (which is why I moved it up to HEAD, to see if
the problem was solved).
Cheers,
Emiel
